1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundRates of conversion procedures after Sleeve Gastrectomy have been reported to reach up to 12.2% in 10 years of follow-up. The aim of this study was to compare perioperative outcomes and weight changes in patients who underwent either conversion from SG to Roux-en-Y Gastric Bypass (C-RYGB) or Duodenal Switch (C-DS).

methodsThis study was a nonrandomized, controlled, retrospective review of 100 patients who underwent conversion of LSG due to recurrent weight gain at our institution from May 2015 to November 2024. Perioperative and postoperative variables were examined.

resultsOf 481 SGs, 100 patients (90 C-RYGB; 10 C-DS) underwent conversion due to recurrent weight gain. The C-DS group had a higher preoperative BMI compared to C-RYGB (57.2 kg/m

conclusionsC-DS appears to be safe and feasible for the surgical management of recurrent weight gain after LSG. In addition, C-DS provides a significantly higher %TWL on 6, 12 and 24 months compared to C-RYGB.
